The advancing functionality of today's electronics products requires ever increasing quantities of internal data transfer
. Once wired connections approach the limit of their data capacity, additional circuitry is required to facilitate larger data transfers, however this leads to the issue of increasingly complicated IC packages, intricately printed circuit boards, and larger IC sizes.
The NEC iStorage Model S4900 series products combine the benefits of the InSpeed SOC 320 with additional state-of-the art technologies such as disk drives carrying rotational speeds of up to 15,000 RPM, a 192GB/s internal data transfer
rate with enhanced Crossbar technology, advanced diagnostic capabilities that enable preventive disk drive maintenance.
An ATA drive's internal data transfer
speed tops out at about 60MB/s--the maximum rate that the data head can sustain reads or writes to the disk media.
The 300GB model has a spindle speed of up to 10,000 rpm and an internal data transfer
rate of 132MB/s.
The Deskstar 37GP gives an areal density of up to 5.3Gbits per square inch and an internal data transfer
rate of up to 23 Mb per second.
It comes in a palm-sized, silver-gray metallic case, featuring 640 MB storage capacity, an internal data transfer
rate of up to 2.55 MB/s, a 2 MB R/W buffer, and 45 ms mean access time.
However, EMC, Hitachi Data Systems, and other companies have developed internal data transfer
functions that copy data between mainframe devices and open systems devices within a storage subsystem.
The new Allegro 5 series drives will deliver the fastest-ever internal data transfer
rate for servers and workstations, said Fujitsu's European technical director, Mike Nelson.
An internal data transfer
rate of 2.55MB/s is possible while a 2MB R/W buffer is also included.
